The invention provides an instrument panel character display method and device. The method comprises the steps: determining the bitmap information of characters to be displayed, and storing the bitmap information of the characters to be displayed in a cached bitmap linked list; generating a first index array according to the attribute information of the character to be displayed and the bitmap linked list node address; searching in a first index array according to the attribute information of the target character; if the attribute information of the character corresponding to the attribute information of the target character is found, reading corresponding bitmap information in a bitmap linked list according to the bitmap linked list node address of the character, and displaying the bitmap information; if the attribute information of the character corresponding to the attribute information of the target character is not found, creating and displaying the bitmap information of the target character, storing the created bitmap information of the target character in the bitmap linked list, and updating the first index array, so the bitmap information does not need to be generated every time, the overhead of a processor is saved, and the character display efficiency is improved.

    本发明提供一种仪表盘字符的显示方法及装置,其中,所述方法包括:确定待显示字符的位图信息,将待显示字符的位图信息存储于缓存的位图链表中;根据待显示字符的属性信息以及位图链表节点地址生成第一索引数组;根据目标字符的属性信息,在第一索引数组中进行查找;若查找到与目标字符的属性信息相对应的字符的属性信息,根据字符的位图链表节点地址在位图链表中读取对应的位图信息进行显示;若未查找到与目标字符的属性信息相对应的字符的属性信息,创建目标字符的位图信息并进行显示,将创建的目标字符的位图信息存储于位图链表中,更新第一索引数组,从而无需每次生成位图信息,既节约了处理器开销,又提升了字符的显示效率。
